Unhandled exception when using vstgui

[justdanpo]

Hello.
I've tried buliding plugins which use vstgui. One of them is generated by vst3projectgenerator, another - VST_SDK\my_plugins\helloworld_with_VSTGUI. They work fine when built with debug configuration and both cause DAWs crashes (Ableton, FL) when bulit with release. editorhost and VST3PluginTestHost execute these plugins well.

vst sdk 3.7.7, vstgui 4.12

I've added debug logging and found this:

!initialized pimpl (CFrame::CFrame)	
!uninitialized pimpl (CFrame::beforeDelete)	
!null pimpl in VSTGUI::CFrame::invalidRect //invalid memory access

beforeDelete() is called from VST3Editor::open

	if (!enableEditing (false))
	{
		getFrame ()->forget ();
		return false;
	}

Ooook, this happens when not full plugin bundle is installed (no .uidesc file available in resources path) which is surely bad, but crashing DAW isn't good either.

Thanks for the report. And you're right, it should not crash.
